Intravascular Imaging- Versus Angiography-Guided Percutaneous Coronary Intervention For Complex Coronary Artery Disease — RENOVATE  

Coronary Artery Disease Clinical Trial

Official title:
Randomized Controlled Trial of Intravascular Imaging Guidance Versus Angiography-Guidance on Clinical Outcomes After Complex Percutaneous Coronary Intervention (RENOVATE-COMPLEX-PCI)

Clinical Trial Summary

The aim of the study is to compare clinical outcomes between intravascular imaging-guided versus angiography-guided percutaneous coronary intervention (PCI) in complex lesions.

Clinical Trial Description

After introduction of the 2nd generation drug-eluting stents (DES), the rates of device-related failure or target lesion failure such as restenosis and stent thrombosis has been markedly decreased, compared with the era of bare metal stents or 1st generation DES. Nevertheless, patients undergoing percutaneous coronary intervention (PCI) for complex lesions, for example, chronic total occlusion (CTO), left main disease, true bifurcation lesion, long lesion, multi-vessel PCI, multiple overlapping stents, or severely calcified lesions have significantly worse clinical outcomes than those with non-complex lesions. During the PCI procedure, intravascular ultrasound (IVUS) and optical coherence tomography (OCT) are useful tools for providing information on preintervention lesion characteristics, including vulnerable plaques, lesion severity, length, and morphology; on postintervention optimal stent implantation for stent expansion, extension, and apposition; and on possible complications after stent implantation. Therefore, intravascular imaging guidance may improve clinical outcomes after complex PCI. However, although previous randomized controlled trial (RCT) and registries showed significantly lower rates of major adverse clinical events following IVUS-guided PCI compared with angiography-guided PCI, the RCTs were limited with small sample size and dealt with very selected lesion subsets such as CTO or long lesion. Moreover, it is uncertain whether OCT-guided PCI improves clinical outcomes compared with angiography-guided PCI. Meanwhile, appropriate imaging modality may differ according to patient and lesion characteristics. One of the ways to maximize the advantage of intravascular imaging is choice of intravascular imaging devices by the operator's discretion. Therefore, the current RENOVATE-COMPLEX-PCI (Randomized Controlled Trial of Intravascular Imaging Guidance versus Angiography-Guidance on Clinical Outcomes After Complex Percutaneous Coronary Intervention) is designed to investigate whether PCI under guidance of intravascular imaging devices (IVUS or OCT) chosen by operators would improve clinical outcomes compared with angiography-guided PCI in patients with complex lesions. ;
